Operands:
S
: Matrix source address
n
: matrix length (K1~K256)
D
: result
Description:
1.
This instruction counts the number of 1s or 0s in a matrix of length
n
, and places the result in
D
.
M1098 determines if the instruction counts 1s or 0s. If M1098=0, it counts the number of 0s in
the matrix. If M1098=1, it counts the number of 1s in the matrix.
2. If
S
uses KnX, KnY, KnM and KnS or if
D
uses KnY, KnM and KnS with an ELC-PC/PA/PH, or
a ELCM-PH/PA, n must equal 4. For the ELC-PV n can be 1, 2, 3 or 4.
3. Flags:
When M1099 is ON, this means the result is 0.
When M1098=1, count the number of 1s in the matrix. When M1098=0, count the number of
0s in the matrix.
Program Example:
When X0=ON and M1098=1, the instruction counts the number of 1s in the matrix D0-D2 and saves
the count in D10. When M1098=0, it counts the number of 0s in the matrix D0~D2 and saves the
count in D10.
